Grendel PrimePASSIVE Each enemy consumed grants 250 bonus armor.
Feast
Swallow enemies whole and store them in Grendel's gut. Hold to vomit out stored enemies, covering them in toxic bile.
Nourish
Regenerate health as Grendel absorbs nourishment from enemies in his gut. While he digests, enemies that attack or are attacked by Grendel suffer Viral Damage and energy sources provide more energy. These buffs extend to squad mates.
Pulverize
Grendel curls into a ball. He heals over time as he rolls, knocking over anyone in his path. Jumping slams Grendel into the ground and generates a damaging shockwave.
Regurgitate
Violently puke out a bile soaked enemy from Grendel's gut, turning the consumed into a toxic projectile. Nearby enemies are slowed and have their armor dissolved by the bile.
CEPHALON FIELD GUIDE
How to play this build.
Tenno. Umbral mods plus Grendel's huge base health clear 700 armour and cap Arcane Persistence. Nourish once every seven seconds, or a lifesteal weapon, tops the pool back up. That is the whole loop.
How it works
Above 700 armour Arcane Persistence caps incoming health loss; Grendel's health pool plus Hearty Nourishment gives a deep buffer.
Heal by casting Nourish every seven seconds or by running a lifesteal weapon (a Hema Coda, Hirudo Coda, an amalgam-mod Zaw, a Sancti Magistar Incarnon slam, or any glaive with Life Strike).
Helminth
Nourish over Regurgitate.
Where it struggles
Needs a healing weapon or disciplined Nourish casts.
Nullifiers.
No mobility identity.
Variants
The Devouring Maw (#053) is the Pulverize DPS Grendel; The Gut Surge (#179) is the Breach Surge nuke.
Who runs this
Players who want a Grendel that tanks level cap while a gun does the work.
